Asked by Autosport – about Mercedes’ position as preferences, Hamilton said: “No, Ferrari must be the favourites. We can’t take our eyes off them because they have been doing such a great job at the moment.
“Red Bull look like they are quite good as well. We’ll see over the next days and, most importantly, over the next weeks, but it’s going to be close in the first race, that’s for sure.
“Just on times it looks like Ferrari might be quickest, and maybe we’re very close with the Red Bull behind.”
Hamilton concluded his Tuesday morning testing early as the team required to fix the car’s damaged floor in time for the afternoon session.
“It didn’t feel spectacular this morning, but there was just some issues we had with tyre temps and with some damage to the floor,” the Brit added.
“That’s why I sacrificed a little bit of my morning to make sure that the car was fixed in time for Valtteri this afternoon.”
